Default Steering issue.

Helping a friend with a two wheel drive dually. When you hit a bump or get up and down movement in the front it starts walking left to right on the steering. If this makes any since. Changed front shocks and steering stabilizer shock. Front end feels tight. No play in tie rods or ball joints. Any body have experience with this. Maybe gear box?

you mean like death wobble or is the truck pulling to one direction after hitting the bump?

I guess death wobble. It's like a gradual left to right motion. Sometimes worse. I don't even like to drive the damn thing. It did spend sometime of its life on a ranch. 110k miles.

the steering damper doesn't even help these trucks, in fact mine is better without one

how is the steering play in the wheel, issue might not be in the front end but in the steering box

You said "gradual" as in slow? If so, check rear axle u bolts, shocks, and bushings.

if everything is tight via picking one front tire up while the other is on the ground and you checked very well for ball joints and wheel bearings, i would suggest having the alignment looked at. if the caster is out of wack, it can cause this issue. being a ranch truck, im betting you have some worn out parts and bushings you may not be seeing.

if the steering box is shot, i can cause some weird stuff to happen steering wise as well but this is by no means an easy diag over the internet. going to have to get some skilled eyes on this

Just giving update. Alignment done, suspension and steering checked out by shop. Still doing the same damn thing. Put a heavy bumper pull on it and doesn't change anything.

I'm still thinking something in the gear box.

Drives straight doesn't pull. But has that bump steer. Feels like the truck is moving 2" left to right in the front

It’s most likely the steering box, some aftermarket pumps can do this too, I’d do a good flush and make sure all the return lines are tight and no air is in the system and go from there.

Ok thanks. I rode in it today for an hour drive. It's scary to me lol. He's use to it. It's also like a bad shock that front right tire feels like it's up and down when it's going left and right if that makes any since. But I was on that side. So that's probably why it feels that away. Shocks are new though. I'm going to do what WV suggested and go from there.

Your location is listed as Dallas. Is that Dallas, TX? If so, my shop is about 75 miles east of you on I-20. We would be happy to fix the issue if you decide you would rather let someone else handle it.
